Re: Cached Forms Don't Submit

When beforeFilter() gets called cake is already rendering the "cached
version".
(see dispatcher::cached() and ViewHelper#__writeFile()).
Regarding to the docs its not recommended to use the callbacks (
http://book.cakephp.org/view/1380/Caching-in-the-Controller ) .
I would probably try to separate the "display" and "save" part into 2
actions or put the form into an
element and cache that element manually, not via cacheAction.
e.g. in your view script

if($this->data || !($content = Cache::read('big_form', 'persistent'))) {
$content = $this->element('big_form');
if (!$this->data) {
Cache::write('big_form', $content, 'persistent');
}
}
echo $content;
